Coffee marbles or coffee pearls,

What a surprise i had when cleaning out and replacing my grind burrs on the Mazzer jolly timer.
After a good vacume cleaning and some toothbrushing on the mazzer parts I unscrewed the dose dispenser in the dose chamber, lifted the dispenser out found to my surprise five perfect round coffee marbles… They first thing i thougt “chocolate truffels” ?? what the f***…..
It seams the fine espresso grind accumalated underneed the dispenser as it turns with every click it pushes some coffee underneeth the dispenser via the aluminium dose pokets, as it turns the grinds can’t go anyware so they are turned over And over much like Rolling à giant snowball 😉
The cavity underneeth the dispenser is aprox. 1cm.

My other grinder with a coarser setting and less oiley coffee
Didn’t have them so i think the darker roasted coffee helped them to stick together….. Lol

I know this is due To poor maintanace on my part but still they are beautifull…

I wonder now how many turns/ click’s are needed to create them. So i reset the counter and In 3 weeks time i’ll unscrew it again and we’ll see….

Lessen learned: regular maintanace is a must. : )

I wonder now:
most cafe’s restaurant’s bar’s have a maintanace contract for their espresso machine’s, they come by 4 times a year to replace; screens, filter baskets, group rings, etc and check pump funtion, temperature and some times even the grind settings and dose amount 😮 …
But never have i seen them replace grindburs, clean grinders etc. still they charge about €300 To €400 per year for maintanace…..
Only those who really care about coffee quality and freshness do their daily/weekly maintanace or replace parts To get the max out of their coffee.
Common knowlidge on maintanace or cleaning are below par for may establishments.
It would be great to see espresso machine suppliers supply maintanance list and cleaning guides with their machines as this would solve some basic coffee quality for many places Selling espresso coffee.

Chicago report

Because of my work for Sara Lee I had the opportunity to visit Chicago.I was asked to do a demonstration there. And because of that I needed an espresso machine and grinder. After two phone calls it was arranged. First call to Kees van der Westen: Who has an Mirage in Chicago? Second call to Tony Dreyfuss, because he has a Mirage. Tony became a very good friend last days. He and his father own the rock and roll roastery Metropolis coffee in the north of Chicago. 

With their master roster Chris and some super baristas are they one of the most popular bars in Chicago.

the Green Mill

Tony also showed me de roasting plant of Inteligentsia coffee. This ‘orange’ place also rocks. Lots of people with tattoos, piercings and other hipster items work with passion and dedication. Result is perfect coffee which they serve in one of the three espresso bars. In that bars also lots of passionate barista with tattoos.  I was very lucky to find 2006 champ Matt Riddle and 2007 finalist Amber Sather in one of the bars near Belmont. They had a wonderful initiative. They gave customers the change to taste their signature drinks they served the judges in the US championships. Those signatures where really good. Probably the best I have ever tasted. Matt’s was with ginger and lime. Ambers with cherry and white chocolate. Both perfect balanced and a smooth finish.


After Tony helped me with the presentation we went to the famous bar Greenmill. This was the favorite bar of All Capone.

We had fun and spoke about coffee all night. Tony thanks for all your help.
